D5D-IN-326 is an orally active delta-5 desaturase (D5D) inhibitor (IC50s: 72 and 22 nM for rat and human D5D in enzymic and cell-based assays). It has no effect on D6D or D9D activity. D5D-IN-326 reduces insulin resistance and decreases body weight in die
AZD6482 (S-isomer) is a potent, selective, ATP-competitive PI3Kβ inhibitor (IC(50) 0.01 μm), which can inhibit insulin-induced in vitro glucose uptake by human adipocytes (IC(50) is 4.4 μm).
Ganglioside GM3 is a monosialoganglioside that demonstrates antiproliferative and proapoptotic effects in tumor cells by modulating cell adhesion, proliferation, and differentiation. It suppresses angiogenesis and reduces proliferation and migration of human umbilical vein endothelial cells (HUVECs) when used at a concentration of 20 μM via inhibition of VEGFR2 and Akt phosphorylation. Ganglioside GM3 induces dissociation of the insulin receptor-caveolin-1 complex from lipid microdomains, functioning as an inhibitor of insulin signaling and contributing to insulin resistance in adipocytes. Ganglioside GM3 mixture contains ganglioside GM3 molecular species with C18:1 and C20:1 fatty acyl chains.
Neuromedin U (NMU) is a neuropeptide first demonstrated to drive smooth muscle contraction.1Translated as a 174 amino acid propeptide, NMU is cleaved to different lengths in different animals. It has diverse receptor-mediated rolesin vivo, as it regulates feeding, vasoconstriction, nociception, and bone remodeling and contributes to obesity, cancer and septic shock.2,2NMU-25 is the active form of NMU in humans. It binds with high affinity to receptors on human left ventricle and coronary artery (KDs = 0.26 and 0.11 nM, respectively), eliciting endothelium-independent vasoconstriction.3NMU-25 also suppresses glucose-stimulated insulin secretion in human islets, and this effect is lost in NMU R165W mutants, resulting in early-onset obesity.4
